Titanium foam builds Wolverine bones - health - 23 September 2010

The X-Men superhero won't be the only one with metal fused into his skeleton if a new titanium foam proves suitable for replacing and strengthening damaged bones. Bone implants are typically made of solid metal – usually titanium. Though well tolerated by the body, such implants are significantly stiffer than bone. This means that an implant may end up carrying a far higher load than the bone it is placed next to, according to Peter Quadbeck of the Fraunhofer Institute for Manufacturing Technology and Advanced Materials Research in Dresden, Germany.

5-HT2A receptor. The mammalian 5-HT2A receptor is a subtype of the 5-HT2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR).[1] This is the main excitatory receptor subtype among the GPCRs for serotonin (5-HT), although 5-HT2A may also have an inhibitory effect[2] on certain areas such as the visual cortex and the orbitofrontal cortex.

5-HT2A receptor

This receptor was first given importance as the target of serotonergic psychedelic drugs such as LSD. Later it came back to prominence because it was also found to be mediating, at least partly, the action of many antipsychotic drugs, especially the atypical ones. 5-HT2A may be a necessary receptor for the spread of the human polyoma virus called JC virus.[3] Downregulation of post-synaptic 5-HT2A receptor is an adaptive process provoked by chronic administration of SSRIs and classical antipsychotics.

Human Trial Suspended Animation Treatment Set to Begin at Mass General. Welcome to the OpenEEG project. About the project Many people are interested in what is called neurofeedback or EEG biofeedback training, a generic mental training method which makes the trainee consciously aware of the general activity in the brain.

Welcome to the OpenEEG project

This method shows great potential for improving many mental capabilities and exploring consciousness. Other people want to do experiments with brain-computer interfaces or just want to have a look at their brain at work. Unfortunately, commercial EEG devices are generally too expensive to become a hobbyist tool or toy. The OpenEEG project is about making plans and software for do-it-yourself EEG devices available for free (as in GPL).
